Specification of Letters Patent.

Patented Aug. 21, 1917.

Application filed October 3, 1916. Serial No. 123,516.

citizen of the United States, residingat Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Railway-Crossings, of which the following is a specification.

My invention relates to railway crossings in which the gap in the intersection of two rails is automatically closed or filled up when a train is passing over the crossing; and the objects of my improvements are, to provide a crossing in which the gap or interruption in the rail is automatically filled up without any motor or any similar me chanical operation; to provide a crossing in which the interruption of the rails is always automatically kept filled up ready for a train in either direction, longitudinally as well as cross-wise; to provide a crossing in which a passing train aut0- matically opens a gap in the crossing rails leaving continuous rails in the direction in which the train is passing; to provide a noiseless crossing; the invention consisting in the construction, combination and arrangement of devices hereafter more fully described and claimed, and illustrated in the accompanying drawing, in which- Figure 1 is a top view of my device.

Fig. 2 is a cross section through my de vice on line 22 of Fig. 1.

Fig. 3 is a side elevation in detail of a modified form of the fillers, bearings being provided on the shafts supporting the fillers instead of having the lower ends of the fillers rockingly mounted on the foundation.

Fig. 4 is the top view in detail of another modified form of the fillers, the shafts being extended and crossing one over another.

Fig. 5 is a side elevation in detail of the modified form of fillers shown in Fig. 4.

Fig. 6 is a side elevation in detail of still another form of filler, the filler being provided with an extension end prO ecting downwardly, two springs engaging with the extension end of the filler between which the extension end of the filler is balanced holding the filler in an upright position.

Fig. 7 is a side View or elevation in detail i of still another form of fillers, a coil spring bein mounted on the pivot of the filler for holding the filler in an upright position.

Fig. 8 is a side elevation in detail of still another form of fillers, a weight being placed and balanced over the cam on the shaft'of the filler between suitable standards.

Fig. 9 is a side elevation in detail of still another modified form of fillers, balancing means being engaged with the lower end of the downwardly extending end of the filler for holding the filler in an upright position. Similar numbers refer to similar parts throughout the several views.

The fillers 1 are secured to the shafts 2, see Fig. 1. The cams 3 are secured to the shafts 2 at a suitable place between the fillers so as to hold the fillers in an upright position when the flat sides 4: of the cams are placed horizontally, see Fig. 2.

"7, and the tops 12 close the gaps in the cross rail 8.

The lower ends 13 of the fillers are rockingly mounted in a recess 14 on the foundation, as shown in Fig. 2. Slight modifications of this support are illustrated in the following figures. In Fig. 3, the shaft 2 is shown as supported in roller bearings 15. In Figs. 4 and 5, the shafts 2 are shown as provided with extension ends 16 crossing one over the other for which a bearing can be constructed as will easily be understood. In F ig. 6 another modified form of the shaft 2 is shown as mounted in the base plate 17 below the rail 18 and the filler 1 is turnably mounted on the shaft with a roller bearing inserted in the filler. In Fig. 7 is still another modified form of the filler 1 shown as being rigidly secured to the shaft 2, which is turnably disposed in a roller bearing 19 below the rail 20.

The wheels 21 of a passing train hit with the flanges of the wheels against the tops of the fillers thereby tipping the fillers over to an inclined position as indicated at 22in Fig. 2. The cam 3, being also rigidly mounted on the shaft 2 with the filler, tips over at the same time with the filler thereby lifting the bar 23, which is pressed down by a spring 24:. As soon .as the wheel has passed the top of the fillen the bar 23, being impelled by the spring 24 presses the cam With the flat top side back to a horizontal position thereby b llg ng t fil er back to upright position. By this operation the gaps in the crossing rails are normally kept closed, and the Wheel indicated at 21 in Fig. 2, While pushing the top 12 out of the gap as described above, passes over the top 9, filling the gap in the rail over which the train is passing. The passing of a Wheel over the op o a filler se n in end, ew is ill trated at 25, the Wheel passing ov r the top 11. p

In ige l a d 2, the her 23 1s sh wn as operating two opposite cams With four fillers, but it Will easilybe understood that the ere ooh b operated ing y,it ill als h unde sto d ha a eight an beueed stead o th spr ng a il u tra ed. i Fig- 8, h Wei h 26 being m n ed b t e n yokes or g ide 27 In g- 6,theflfi .er nro id With e et-dly xtendi g endZtS, hich is balan d een th spr ngs .29 nd n iig-l e p i g 3 is embed low the rai 20 eu r hd ngthe sh t being eonn t d h n end 32 to the shaf 2 and i h the other en 3 o the i o as Plate I F ge pring a is e gaged with the ardly eX end g end h i h filler a y n a p g pos ion Instee o he sp i g 34, a eigh n be sed with advantage as will easily be understood.

A Weight would always be the same and not failing Which might occur With a spring.

Having thus described my invention, I claimzm r 1- In a railway messing, a shaft mounted longitudinally below each of the short rails in crossings, fillers secured to the ends of the shafts having tops projecting upwardly into the gaps of the rails flush Withthe tops of the. rails, a fiat-face member secured to the shafts between the fillers, and means mounted adjacent the flo faoe. members for pressi g gains e fl feeee f the sa d memher adapted, to ser e as balan ing means for the fillets- 2- In a rai ay crossing, a shaft m un ed longitud nally below each of he sho rails of the crossing, ll r secured to he sh ft projecting norma ly upwar ly into th g p at the ail ineans n t e, h fts fo ming two Pr jec io s. rans ersely of the shat i h Pr jections be ng n the oppo ite sides of th shafts in relation to. e eh her on eaeh an means mo nted n ar t e shat s ngaging ith the p ojection for automatically holding the til ers in normal. upright position yi lding y- In te tim ny hereof I he eunto my eigna ein th pre nce o two tnesses- FRAN L- .GILMAN.
